On each of its turns, the spy can use a bonus action to take the Dash, Disengage, or Hide action.

Sneak Attack (1/Turn)

The spy deals an extra 7 (2d6) damage when it hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 ft. of an ally of the spy that isn't incapacitated and the spy doesn't have disadvantage on the attack roll.
